You’ve probably heard at some point that what you eat can have an impact on how your vagina, um, smells and tastes. Some people even say that pineapples and pineapple juice make you sweeter down there—a claim that Kim and Kourtney Kardashian once tested out on their show.

But is there any legitimacy to this?

Unfortunately, there haven’t been any scientific studies conducted that connect diet with the flavor and smell of vaginal discharge (although the Kardashians found that pineapple juice did make everything smell sweeter).

But Jessica O’Reilly, Ph.D., Astroglide’s resident sexologist, says there may be something to it. “We can’t ignore the anecdotal evidence from experts and the general population,” she says.

O’Reilly's clients have reported that eating sweet fruits, vegetables, and herbs can “temper the taste of vaginal discharge to heighten its sugary flavor,” she says. “They also suggest that smoking, caffeine, and preservatives can result in a more bitter taste.”

Medications may also mess with things down there. O’Reilly says antibiotics that affect your good vaginal flora levels may cause “less desirable changes in taste.”

What kind of timeframe are we talking about here? O’Reilly says people tend to notice a difference within a day after eating a particular food, and it typically lasts for up to two days.

But, if you want to mix things up a little, she recommends cutting back on how many preservatives and highly processed foods you eat. “If the changes in taste relate to yeast, you might also consider cutting down on refined sugars, yeasts, and alcohol while increasing your intake of coconut oil, essential fatty acids (e.g. nuts), whole grains, garlic, and probiotics,” she says.

You can also ramp up your intake of sweet fruits like pineapple and mango, and see where that gets you.

Since there’s no science to back this up, there’s really no guarantee it’ll work. But, if legions of women are to be believed, you really are what you eat—especially when it comes to your vagina.
